IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 217,175, dated July 1, 1879; application filed March 24, 1879.

To all whom it may concern:

Be it known that I, FREDERICK D. TUTTLE, of Owatonna, in the county of Steele and State of Minnesota, have invented certain new and useful Improvements in Pumps, of which the following is a specification.

Figure l is a vertical central section, showing the operative parts of the pump and the induction and eduction pipe connection. Fig. 2 is a plan view on line as m of Fig. 1. Fig. 3 is a top plan of the device. Fig. 4 is a plan view of under side of the valve-plate. Fig. 5 is a vertical central section of the device and at right angles to view in Fig. 1. Fig. 6 is a horizontal plan view on line .00 w of Fig. 5. Fig. 7 is a perspective, showing more plainly the internal construction of the device.

The present invention belongs to that class of pumps which act both by force and suction, and can more distinctively be called a double-acting and force and suction pump and the novelty consists more particularly in the special detail of arrangement and construction of the parts, whereby an effective and very useful device is produced, all as will now be more in detail set out and explained.

In the accompanying drawings, A denotes that part of the pump which is usually known as the cylinder, and this may be made in any usual or desired shape. The plunger 0 works in the circular chamber B, which extends the length of the cylinder or part A. Adjoining the chamber B, and also extending parallel with it for the length of A, are two chambers or spaces, D and E, of irregular shape in horizontal plan.

The partition between the cylinder B and the chamber E is cut away at its lower end, so

as to leave an open free water space or way, 0,-

between the lower end of the cylinder B and the chamber E, and a similar opening, d, is made in the partition between the cylinder B and chamber D at their upper ends, so that there is a free passage for water between the cylinder B and chamber E at their lower ends, and an opposite free passage of-water between the cylinder B and chamber D at their upper ends.

The piston O has a small opening, 0 made through it, over which aclappervalve is placed,

opening upward. The opening 0 is made much smaller than the openings 0 d, and by its employment less power is required in operating the piston in its downstroke.

At the lower end of the cylinder A is an induct chamber, F, which connects with the chambers B and D, respectively, by means of apertures '11 and 01, each of which is suitably provided with a clapper or other valve. the under side of this induct-chamber F is an opening, f, provided with a collar, for the at tachment thereto of a pipe of iron, wood, or any suitable material to extend into or reach the water in the well. Likewise on the other end, in top of the cylinder A, is an eductionchamber, G, which, in like manner, has valved connections I) and c with the chambers B and E.

To the collar on the opening g a suitable eduction-pipe can be secured. Gas-pipe can be used for this purpose. The plunger-rod c is operated by any suitable means.

The device as thus made can be set in the bottom of the well, or half-way out of. it, or even on the top, when the well is not too deep,

and can in either. situation be worked easily and eficctively.

In the downward movement of the piston G the valve over the opening b will be closed, and the greater part of the water in the cylinder will be forced through the opening 6 up through the chamber E, and from thence through the opening 0 out of the pump. The perforation or opening 0 in the piston will be opened, and a portion of the water in the cylinder will pass above the piston C; but as the difference of area between the opening in the piston and the opening 0 is large, the greater part of the water in the cylinder will be forced into the chamber E.

In the upstroke of the piston the opening in the latter will be closed by its valve, and the water above the piston will be lifted and ejected through the opening d into the cham ber D, and thence into the cduction-chamber, and suction below the piston will occur, thereby rendering the pump a double-acting, forcing,

lifting, and suction pump.

Having thus described my invention, what I consider new, and ters Patent, is-
